Run all the tests, or the selected TESTS, and save a detailed log file.
Upon failure, create debugging scripts.

You should not change environment variables unless explicitly passed

to exercise.  Each relative directory is expanded as build and source
directories relatively to the top level of this distribution.  E.g.,
